Descripción
A search is presented for supersymmetry in all-hadronic events with
missing transverse momentum and tagged top quarks. The data sample was
collected with the CMS detector at the LHC and corresponds to an
integrated luminosity of 2.3 fb-1 of proton-proton collisions
at a center-of-mass energy of 13 TeV. Search regions are defined using
the properties of reconstructed jets, the multiplicity of bottom and top
quark candidates, and an imbalance in transverse momentum. With no
statistically significant excess of events observed beyond the expected
contributions from the standard model, we set exclusion limits at 95%
confidence level on the masses of new particles in the context of
simplified models of direct and gluino-mediated top squark production.
For direct top squark production with decays to a top quark and a
neutralino, top squark masses up to 740 GeV and neutralino masses up to
240 GeV are excluded. Gluino masses up to 1550 GeV and neutralino masses
up to 900 GeV are excluded for a gluino-mediated production case, where
each of the pair-produced gluinos decays to a top-antitop quark pair and
a neutralino.
